Add support for OpenBSD, and also add some regression tests.

Add info about OpenBSD support to README.md and metadata.json
Add a note about OpenBSD java_version fact to README.markdown.
Fixup wording on context in one of the java patch level regression tests.
No mentioning of OpenBSD in metdata.json

Cleanup wording of context as suggested by @elyscape
update contexts as suggested by @elyscape

+### A note to OpenBSD
+OpenBSD packages install Java JRE/JDK in a unique directory structure, not linking
+the binaries to a standard directory. Because of that, the path to this location
+is hardcoded in the java_version fact. Whenever a Java upgrade to a newer
+version/path will be done on OpenBSD, it has to be adapted there.

 ##Development
 
 Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad hardware, software, and deployment configurations that Puppet is intended to serve. We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things. For more information, see our [module contribution guide.](https://docs.puppetlabs.com/forge/contributing.html)
